For example, two wires 91 located in Fig. 4 are electrically connected to two ends (see Fig. 5) of coil 36.Lead 91 can be from shell Expose in body 6, wherein wire is attached to coil 36.
Illustrated referring now to operations of the Fig. 1 to Fig. 4 to the electromagnetic relay 1 according to embodiment 1.Specifically, to The operation of the electromagnetic relay 1 of emergent shutdown when abnormal current flows through is illustrated, and the abnormal current is to break down When electric current I2.Emergent shutdown when if electromagnetic relay 1 is used to break down, usual coil current I1 flowing through coil 36 is simultaneously And fixing terminal 41 and movable terminal 42 are (ON states) in the conduction state.Generally, less electric current further flows through fixing end Son 41.Normal current I2 current value, for example, be tens to hundreds of amperes.
The initial operation before normal operating first to electromagnetic relay 1 illustrates.In moving contact 21 with fixing In the state of contact 22 separates, when the switch (not shown) connected with coil 36 is changed into open mode from closed mode, online Apply voltage and coil current I1 flowing through coil 36 on circle 36.When coil current I1 flowing through coil 36, in electromagnet device The first magnetic flux is produced in 31 iron core 37Electromagnet device 31 passes through the first magnetic fluxAttraction driving armature 32, And armature 32 is thus set to be pivoted along the counter clockwise direction in Fig. 1.When armature 32 pivots, contact spring 23 is pulled on card 34 It is bent upwards in Fig. 1, moving contact 22 contacts fixed contact 21.Fixing terminal 41 and movable terminal 42 are changed into conducting state (ON State).In this case, the first magnetic fluxIt is bigger, therefore iron core 37 attracts the attraction used in armature 32 to become big.
Next the normal operating to electromagnetic relay 1 illustrates.In normal operating, when above-mentioned switch becomes from opening During to close, voltage is removed from coil 36 and coil current I1 stops flowing through coil 36.When coil current I1 stops flowing through During coil 36, armature 32 pivots along the clockwise direction in Fig. 1, and then moving contact 22 separates with fixed contact 21.It is fixed to touch Point 21 and moving contact 22 are oppositely located relative to each other, and have gap therebetween, because when not applying voltage on coil 36, card 34 Contact spring 23 will not be pulled.In this case, fixed contact 21 and moving contact 22 are changed into nonconducting state (OFF shapes State).
It is in fixed contact 21 and movably tactile when fixing terminal 41 and movable terminal 42 are from ON state changes to OFF state Arc discharge may occur between point 22.When arc discharge occurs, preferably extinguish arc discharge rapidly so that short Arc discharge is completed in time.When electric current I2 occurs as the failure that flows through of abnormal current with exceptional value, especially, different Constant value is than much bigger, it is necessary to complete arc discharge immediately in normal operating.
When above-mentioned abnormal current flows through fixing terminal 41 and movable terminal 42 as electric current I2, opened with what coil 36 was connected Close (not shown) is the electric current I2 of abnormal current and is changed into closing from opening in response to detecting.Due to not applied on coil 36 Therefore making alive, coil current I1 stop flowing through coil 36.In this case, exist in the iron core 37 of electromagnet device 31 Remanent magnetization.Due to the magnetic flux of remanent magnetization firstIt is still present in armature 32.It is, even if coil is electric Flow I1 and stop flowing through coil 36, remanent magnetization is still suffered from iron core 37, thus prevents the first magnetic fluxImmediately become Zero.
It is configured to generate the second magnetic flux by the electric current I2 for flowing through fixing terminal 41 according to the electromagnetic relay 1 of embodiment 1 AmountWithTo stop reducing by the first magnetic flux after flowing through coil 36 in coil current I1Influence.It is specific next Say, because the first Crossware 413 and the armature 32 of fixing terminal 41 intersect, when electric current I2 to upside flows through from Fig. 1 downside During the first Crossware 413, the second magnetic is produced along Fig. 2 counter clockwise direction around the first Crossware 413 of fixing terminal 41 FluxIn armature 32, the second magnetic fluxDirection with as caused by coil current I1 the first magnetic fluxSide To opposite.
Further, since the second Crossware 414 of fixing terminal 41 intersects with armature 32, when electric current I2 flows through the second Crossware When 414, the second magnetic flux is produced along Fig. 1 counter clockwise direction around the second Crossware 414 of fixing terminal 41 In armature 32, the second magnetic fluxDirection with as caused by coil current I1 the first magnetic fluxIt is in opposite direction.
As described above, in armature 32, the second magnetic flux for being generated by electric current I2WithIt can reduce by coil electricity Flow the first magnetic flux of I1 generationsInfluence.Therefore, with fixed contact and moving contact by supporting moving contact Supporting member may increase beating for fixed contact 21 and moving contact 22 compared with the electromagnet relay for the configuration that armature separates Open speed.
Operation when being separated to moving contact 22 with fixed contact 21 is described in detail below.Even in coil electricity Stream I1 stops producing for reducing by first magnetic flux as caused by the remanent magnetization of iron core 37 after flowing through coil 36's The second magnetic flux influenceedWithThe magnetic flux of reason firstCaused attraction, armature 32 are still attracted to iron Core 37 with iron core 37 without separating immediately.
However, the elasticity rate suction of contact spring 23 is big, therefore armature 32 will separate with iron core 37.When contact spring 23 When separating to a certain extent with iron core 37, the speed that armature 32 separates with iron core 37 becomes big.Therefore may be from coil current I1 Increase opening speed in a period of time when being separated when stopping flowing through coil 36 to moving contact 22 with fixed contact 21.
Generated as described above, increase opening speed makes it possible to extinguish rapidly between fixed contact 21 and moving contact 22 Arc discharge.
In order to realize the rapid extinguishing of the arc discharge generated between fixed contact 21 and moving contact 22, according to implementation The electromagnetic relay 1 of example 1 is provided with the arc extinguishing component 11 for example including permanent magnet 111 and yoke 112.It is, permanent magnet 111 Magnetic field is formed to elongate electricity by the electromagnetic force obtained from magnetic field around fixed contact 21 and moving contact 22 with yoke 112 Arc, so as to extinguish electric arc.
